Harken Carbo AirBlocks 29 mm - 75 mm
Strong, compact, low-friction and lightweight.
Carbo AirBlocks® are strong, reliable and affordable. Ideal for smaller diameter lines for both racing and cruising.
Similar design to their bigger brother, the popular Harken® Black Magic® line, the smaller carbo Airblocks have very high working loads for safe, easy trimming no matter how hard the wind blows. Side plates of high-strength resin are UV-stabilized to provide excellent protection against long-term exposure to saltwater and sun.
Very Light and Strong - Carbo blocks use densely packed glass fibre reinforced nylon resin side plates to replace stainless steel straps and are 30% lighter with a 60% higher working load than Classic blocks. Open AirBlock® design eliminates unnecessary material and weight.
Long Lasting - Ball bearings, sheave, and side plates are UV stabilized with carbon black for maximum protection. Three-Way Cam-Lock Patented switch locks shackle in front or side positions, or lets block swivel to keep line from twisting.
